Application September 4 Claims.

'I'his invention relates to upholstery construction. It is particularly directed to strip webbing for seats and means for fastening the strips to the seat frames, and the like upholstered articles.

holstery construction ofthe character described, having improved frictional gripping means for attaching the ends of webbing strips to a frame and including means to increase the frictional grip on the strips with increase vof load on the webbing, the means for increasing the frictional grip on thewebbing being resilient to provide a yield between the webbing and the frame.

A further object of this invention is to provide scribed highly improved and compact yielding means for attaching the webbing to a frame, which shall be located wholly close to and disposed longitudinally ofthe frame wall to which 20: it is attached, whereby to permit foundation springs being placed on the webbing also relatively close to the frame walls.

Another object of this invention is to provide strong and durable vwebbed seat construction of the character described, which may be economically manufactured, easily assembled, which will not tear the webbing, yand whichv shall yet be practical and eflicient to a high degree in use.

Other objects of this invention will in part be obvious and in part hereinafter pointed out.

The invention accordingly consists in the features of construction, combinations of elements, and arrangement of parts which willbe exempliiiedin the construction hereinafter described, and of which thevscope of application will be indicated in the following` claims.

Fig. 10 is a cross-sectional View taken on line IIl--Ill of Fig. 9.

Referring now in detail to the drawings, I0 designates upholstery construction embodyingthe invention, here shown for the purpose of illustra-y the endswhereof are attached to the frame walls in accordance with my invention, as described hereinafter. i

Each of the strips I9 running .from front to rear is attached to the front wall I4 *by attaching means embodying the invention. The rear ends of the strips I9 are attached to the rear wall I5 by another attaching means 2|, likewise embodying the invention. l

The attaching means 26 comprises a tube 23 disposed parallel to the bottom edge of wall I4, and having a longitudinal slot 24. Said tube 23 may be formed with a pair of aligned longitudinal slots or notches 21 at the ends thereof' diametrically disposed with respect to slot 24. Within said tube is a pin 22 disposed parallel to said slot.'

One end of strip I9 is folded or looped around pin .22 and passes through slot 24. Tension on the strips I9, due to pressure on the webbing, causes the pins 22 in the tubes- 23 to press the folded over portions ofthe strips against the edges 24a. of the tubes at said slots 24, whereby to frictionally fasten or clamp the strips to said tubes. The edges 24a are preferably beaded or rounded so as not to cut into the webbing or tear the same. l

Extending through each tube 23 is a spring wire or rod 26 projecting beyond the tube at both ends, the ends of said rod being received in the slots or notches 21 of the tube. Attached to the frame wall I4 on opposite sides of each tube 23, are a pair of angle-shaped brackets 29, each having arms 30 and 3| xed to the inner surface and bottom edge of the frame wall by nails or otherA suitable fastening means. The arms 30 of said brackets are formed with humped portions or ears 3Ia receiving the ends of the wire or rod 26.

As load is increased on the webbing, the middle of the wires or rods 26 become bowed to press the pins 22 toward the slots 24 and thus increase the friction on the webbing. The wires or rods 26 being made of resilient metal will yield to provide resiliency at the ends of the webbing strips. vSince the foundation springs on the webbing are tied down to the frame, there is always pressure on the webbing which is hence always under tension to maintain the frctional grip.

It will be noted that the tubes 24 are disposed substantiallyl close to the frame wall somewhat above the lower edges thereof. Said tubes do not lother preferred form of my invention.

project an appreciable distance inwardly from the walls, and hence foundation spring may be placed on the webbing relatively close to said walls. 'Ihe webbing strips I9 may be attached to the front frame wall I4 and the side frame walls I6 in the manner described above.

'Ihe means 2I for attaching strips I9 to the rear wall I5, as illustrated at the righthand end of Fig. 2 of the drawings, and in Fig. 5 of the drawings, comprises tubes. 230i` likewise provided with longitudinal slots 24. Within tubes 23a are pins 22. 'I'he rear ends of strip I 9 are folded over said pins and pass through slots 24. Each tube 23a is provided with a pair of spaced, integral, punched, strap portions 35. Coil tension springs 36 interconnect the: vstrap portions 35 with brackets 29 Xed to the r'ear frame wall I5. The hooked ends 36a of 'springs 36 may press the pins 22 toward slots 24 to retain a strong frictional grip on webbing.

In Figs. '7, 8, 9 and 10 there is shown a fastening means 29a, for attaching the ends of the webbing strips I9 to the frame walls, illustrating an Said means 26a. comprises an elongated member 49 of angular cross section, disposed parallel to the lower edge of the frame wall and having longitudinal, angularly disposed walls 4I and triangular-shaped end walls 42 formed with apertures 43. The edges 4Ia of walls 4I and edges 42a of end wallsl 42 form a rim for the open side of member 49, which open side is contiguous and parallel to the inner surface of the frame wall. The meeting edge between the walls 4I of member 40 is preferably slit longitudinally and the slit edges bent or curved outwardly as at 44 forming a slot 45 therebetween.

Within the member 49 and adjacent and parallel to slot 45, is an angle-shaped member 41 having angularly disposed walls 4S. The angle between the walls 48 is preferably the same as the angle between the walls 4I. The outer edges of said walls 48 are preferably beaded or rounded as at 49, for the purpose hereinafter appearing.

said strip against the inner surfaces of the walls 4I to frictionally clamp the strip to member 49. Fixed to the frame wall on opposite sides of the member 40 are a pair of brackets 29. Extending within the member 4l) is a resilient wire or rod 26, the ends whereof pass thr'ough the apertures 43 and engage within the humped portions or ears 3Ia. of said brackets 29. As shown in the drawings, the middle of the wire or rod 26 is bowed inwardly and presses the webbing within the member 47 and into contact with the inner surfaces of the walls 48 thereof. The greater the tension or downward pressure on the webbing, due to increased load on the foundation springs supported by the webbing, the greater will be the 1 pressure of the wire 26 against the webbing to increase the friction on the folded over' portions of the strip I9.

Since the portions 44 of the member 40 are rounded and are outwardly, danger of tearing zthefstrip is eliminated. The angle shaped memframe to aid in supporting loads imposed on the 4changes might be made in the embodiments above set forth, it is to be understood that all matter herein set forth or shown in the accompanying drawings is to be interpreted as illus trative and not in a limiting sense.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:
